We know that there are many raw materials for resin cutting disc, and abrasives, bonding agents. And voids are the main ones. Abrasives include brown corundum (A), white corundum (WA), black silicon carbide (C) and green silicon carbide (GC), as well as chromium corundum (PA), single crystal corundum (SA), microcrystalline corundum (MA) , Zirconium corundum (ZA), SG abrasives, etc. The bonding agents include ceramics, resins, and low temperature bonding agents. Today we will talk about brown corundum, the main material of the grinding wheel.
Brown corundum, as one of the raw materials for cutting chips, has its own advantages. Due to the performance advantages of minerals, high hardness, good toughness, high specific gravity. And no harmful substances, brown corundum is a natural environmentally friendly grinding material. So many grinding wheel manufacturers and countries will choose for environmental protection considerations. Brown corundum is used as the main material of resin grinding wheel.
One, High grinding efficiency
Brown corundum has high hardness, strong grinding ability and sharp edges and corners. Under a certain pressure, it can quickly hit the surface of the object with sharp edges and corners, and can quickly and effectively grind the surface of the object. So it is regarded as one of the very sharp raw materials.
Two, Low loss
The unique particle size of brown corundum ensures that more effective particles hit the surface of the object (such as 30-60 mesh sand, 11 million particles per kilogram can hit the surface of the object, while conventional slag such as 20 mesh can only produce 1 million particles Impact on the surface of the object), so that the use of garnet sand can greatly reduce the loss of abrasives-usually can save 1/3 of conventional abrasives.
Three, Environmental protection and cheap
Unlike conventional materials, brown corundum is a pure natural non-toxic mineral, which does not contain free silicon harmful substances that cause silicosis, and does not contain toxic heavy metals or radioactive pollutants. In addition, silicon carbide and white corundum are much cheaper compared to the same period in the market, and they are also one of the first choices as the main raw materials for cutting chips.
Four, Can be recycled
Brown corundum is very suitable for many fields. Under normal circumstances, it can be reused 5-10 times. If it has not lost its cutting ability after 10 times, the number of cycles can be more. However, it should be noted that the site needs to be kept clean during use, so that it can be recycled again when it is recycled. After it has no cutting ability, brown fused alumina can be recycled and used in the construction industry as a cement additive.
The above is the advantage of brown corundum as a raw material for cutting disc, sorted out by Damon grinding wheel. Corundum is an ideal high-efficiency environmentally-friendly blasting material, and it is worth trying to use by domestic enterprises.
